Sure thing! We've got 147 and we're gonna multiply it by 25. That's the same as adding 147 to itself 25 times.
Step 1: 0 + 147 = 147
Step 2: 147 + 147 = 294
Step 3: 294 + 147 = 441
Step 4: 441 + 147 = 588
Step 5: 588 + 147 = 735
Step 6: 735 + 147 = 882
Step 7: 882 + 147 = 1029
Step 8: 1029 + 147 = 1176
Step 9: 1176 + 147 = 1323
Step 10: 1323 + 147 = 1470
Step 11: 1470 + 147 = 1617
Step 12: 1617 + 147 = 1764
Step 13: 1764 + 147 = 1911
Step 14: 1911 + 147 = 2058
Step 15: 2058 + 147 = 2205
Step 16: 2205 + 147 = 2352
Step 17: 2352 + 147 = 2499
Step 18: 2499 + 147 = 2646
Step 19: 2646 + 147 = 2793
Step 20: 2793 + 147 = 2940
Step 21: 2940 + 147 = 3087
Step 22: 3087 + 147 = 3234
Step 23: 3234 + 147 = 3381
Step 24: 3381 + 147 = 3528
Step 25: 3528 + 147 = 3675

So, 147*25 = 3675
